VoIP Network Design
The VoIP Network Design provides detailed planning for a new or expanded VoIP Network Deployment. ECG's designs are straightforward, elegant, and manageable. Our designs draw from our experience with dozens of VoIP Service Providers in the US and worldwide.
Product Goals & Assumptions
Collect and understand the Service Provider's product and service goals, and expectations about growth.
Existing Network Core
Understand the Service Provider's existing core network routing and switching equipment and links. Assess the utilization, reliability, and QoS of those links.
Identify new equipment recommended to support a new VoIP deployment, or identify equipment that can be re-used. Design for adequate capacity for five (5) years of projected growth.
Plan new IP subnets and VLANs to support reliable, scalable VoIP system. Ensure compatibility with detailed subnet requirements for VoIP equipment. Provide VLAN and IP address assignments, along with routing rules and protocols.
Collect reliability and fault-tolerance goals, and plan network equipment and protocols to achieve those goals. Analyze failover behaviors based on specific equipment in use.
Design Firewall and Session Border Controller rules or equipment to protect VoIP core switching against theft of service (fraud) or interruption/denial of service. Design MPLS-compatible Virtual Routing and Forwarding (VRF) instances as needed. Recommend equipment placement, and specific firewall rules to support VoIP application.
Quality of Service
Design effective mechanisms for guaranteeing toll-quality audio and faxing for VoIP, including prioritization or bandwidth guarantees across links and routers. Recommend appropriate packet markings.
Plan physical connections for VoIP equipment, accounting for fault-tolerance objectives and hardware capacity limitations.
Management & Control
Design appropriate tools for management, surveillance/packet capture, monitoring, DNS, and time synchronization.
The VoIP Network Design provides a detailed Design Package, typically 30 pages or longer. It is suitable for immediate implementation by an experienced IP network technician.
When to do it? The VoIP Network Design takes place after VoIP equipment has been selected (media gateways, call servers, media servers, etc.), but before network core equipment decisions are finalized, and before the VoIP equipment has been installed. Detailed follow-up discussions with our Technical Staff are included.
